The pressure convertor calculates pressure using the following conversion factors:

*1 standard atmosphere = 1.013250 x 10*^{5} Pascals

*1 technical atmosphere = 9.806650 x 10*^{4} Pascals

*1 Bar = 1 x 10*^{5} Pascals

*1 Mercury (in Hg) = 3.38638 x 10*^{3} Pascals

*1 Mercury (mm Hg) = 1.33322 x 10*^{2} Pascals

*1 PSI = 6.894757 x 10*^{3} Pascals

*1 Torr = 1.33322 x 10*^{2} Pascals

*1 Inches of Water (in H2O) = 2.49082 x 10*^{2} Pascals
